T0 is, whom, (it may conccrm Be it known that 1, CHARLES E. WiLLn'y, e citizen of the United States, residing at Louisville, in the county of Jefiferson and. State of Kentucky, have invented certein new end useful Improvements in Drilling Machinery; and do hereby declare the following; to be :t full, oleer, end exact description of the vention, snch will enable others skilled. in the ert to which it eppertsins to make and use the same.

lily invention relates to improvements in lrilling-1nsehines, and more particularly to improvements in redial end semirsdisl drills,

My invention consists in mounting an eleciric or other motor onthe redial arm, heeci, or of the drill, and preferably between the supporting-column end the drillspintlle, in driving therefrom gearing by which the spindle is rotstetl and the feed niechenisin opereteii,

lily invention consists, i'ni"ther,'in providing elevating mechanism by which the head iney he reisetl or lowered, said elevating mechanism being also driven from the motor in the head, in forming the pole-pieces of the motor as integral parts of the head, and in the men y novel details of combination, construction, and arrangement of the per-ts.

The objects of my invention are to simplify the structure of drilling machinery, and particularly of radial and seinirsiliel drill-presses, to dispense with the devices ordinarily employed for transmitting motion from a counter-shaft occupy i'ng it fixed oosi tion to the movable head or cerrisge of the machine, to evoirl theme of belts, splineo transmitting-shafts, and the 1'3 power is orinerily communieetecl GO .6 mechanism of the movable he d, o e 6 l and to meke'the mechanism of ilill ple, compact, and self-conteineol, it easy to start end stop-the firili, to Vet! speed, to raise or lower its heed, orito is its head to one side or the other at will, redial and sernirediel drills are ordinarily co: structed power is commnni'ceteil i c i e co ,4 ter-sheft occupying a iizecl position with re spect to the machine and often or usua ly placed at the base of the-machine to spinLlle-driving and automatic feeo. mes ism through the medium of belts or s netl shafts the like. To permit the raising; and of the heed, to permit it to he swung); from one side to the other, end, case of redial drill, to the heeii tohe moved in end ont the radial arm involves the use of transmitting mechanism of considerable complication for the transmitting of "notion iron: the counter-shaft ebove ineetioneil to the drill-seinrlle end its feeding devices. All of this complication be overcome by mounting at prime motor directly in or on the (irill'cerrying heed of the machine, end motor may he so mounted end. conveniently meshed pieced out the Way and protected f om njury by locating: the motor in the (lrv l-eerr iieefil of the .cliine. By so doing all oi the complication 'ncicient to the transmission power from a ixetl conntensheft to e verticelly, laterally, and often radially movable dr "1 heel or cerriege is entirely evoiilezl. This is l -:.lo in the machine herein. ill nstrstetl end l6- scribed.

in the machine herein illnstretecl and i6- scribed, the motor shown not only as carried by the heeoi, but as inclosccl Within same. This is advantageous as protecting the motor from injury, as providing structure of the greetest simplicity least weight. Further, the inotoris arranged with its drive or erinetnre shaft in e horizontal plane and located between the drill-spindle and the support. This is an important feetnre of the invention. The weight of the motor is disposed nearest the point of support, and hence the least strein is exerted on the head. The working or movable parts of the motor, together with the heaviest portion of J the wearing, revolve noon horizontal beerii.

Uporitlie shaft 19 is bevel-pinion 2'7, intermeshieg with a beveLgeer 28., mounted upon "vertioel shaft 29, having bearings in. the heetl 5. The end of the shaft 29 projeote above the top of the heecl and carries a pin ion 36, intermeeliing" with gear 31, eurroiinob ing the drili-egiindle 6 and. eomleotecl thereto by a spline the ordinary manner.

A i13LQ,-Zl-Wl166l -11 is epiined; to el eit 4:0 encl is provided with a cone 42, lying Within a conioel recess in the bevehgear 39 and forming a oone-olutch, by which gear 39 may be placed.

The ooeetroetion liere described. is eulostentielly commonly employed for throw- 'l 'iflj in out the en toii'ieiio feetl of, 3, e; .iie-tool.

The wormelieft carries a. WOl'lll 43, m Worm-Wheel mounted poo feed. elmit 25. Upon eeizl and connected thereto by a. spline is projeotiogx handles 47', my may be rotated.

The meehenism above deeoribecl comprises til meclmnisiii for rotating the drillepimlle, i'or automatically feeding; the some both by power and by hand, and for quickly raising; and lowering the same. I have also provided mechanism. for automatically raising or low-- ering the 5. Upon the lower-end of the 60, ca rying tlie cone-pulley 33 and gear 32, there is a. gear 61, intermeehing; with e 62. (Shown in dotted linee in Fig. 2.) Gear 62 iiiterinesliee with another gear 68, which letter gear intermeeliee with a gear 64., which forms a part of e screw-nut surround an. elevating-screw (35, mounted alongside of the column 2 Gears 62 and 63 are carried e bracket 66., pivoted concentrically on a. screw 55,Wl1il1 bracket is provided with a. lion- (lle 67, by which it maybe moved. By moving" said lizmdle inward out of mesh with gear 61, end by moving sold handle still farther gear 63 may be brought into mesh with gear 61, gear 62 being then an idler. "When. gear 62 is in meal: with rem? 61 if the motor be operetecl tlio l aeecl 5 will be shaft 40 or may gear 62 may be thrown tion between gear 31 and moved in one direction, and if gear 63 be in mesh, the motor being operated, the head will be moved in the otherdirection.

Upon one side of the head is a startingrheostat 68, and upon the other side of the head in the vicinity of the column 2 is a speedregulating rheostat 69.

In the operation of this drill when the armature-shaft revolves power is communicated through the back gears 21 and 23 to the shaft 19 or directly to said shaft if gears 21 and 23 be out of operation, and from shaft 19 power is communicated through bevel-gears 27 and 28 to shaft 29 and pinion 80. From pinion 30 motion is transmitted to gear 31 and thence to the drill-spindle 6. The revolution of the drill-spindle is independent of longitudinal motion thereof, because of the spline connecspindle 6. From pinion 30 motion is also transmitted to gear 32 and thencerthrough the cone- pulleys 33 and 35 to shaft 34; gears 36 and 37, bevel-pinion 38, and bevel-gear 39. If the cone 42 of the feed-wheel 41 be in contact with the conical recess of gear 39, then the drill-spindle is fed downward slowly and automatically by the pinion 50 and rack 51, pinion 50 being driven from hand-wl1eel41, worm shaft 40, worm 43, worm-wheel 44, friction-cone 46, and shaft 45.

he automatic feed may be stopped at any time by turning the nut 42 The drill may be fed in either hand when the automatic feed is not in operalion by means of hand-wheel 41.

For quick adjustment of the position of the drill or for quickly raising the same the clamping-nut 48 may be relieved and the required adjustment obtained by turning the handles 47. \Vhen the clamping-nut 48 is in contact with the wheel 44, the drill is held stationary, except as it may be moved in either direction by the automatic feed or by turning the wheel 41 by hand, owing to the self-locking action. of the worm 43 and the worm-wheel 44.

To raise or lower the head 5, the clampingnuts by which said head is clamped to the column 2 are first relaxed, and then the handie 67 is moved in the proper direction, so as to bring gear 62 or gear (53, as the case may be, into mesh with gear (31.

Having thus completely described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. In a drill, the combination with a support, a head movably secured thereto, and a revoluble spindle carried by said head, of a motor mounted within said head, and carried 1 thereby, the drive-shaft of said motor being arranged horizontally and located between said support and said revoluble spindle, a pinion carried by said drive-shaft, back gearin-g driven by said pinion, a bevel-gear connected to said back gearing, a vertical shaft, a bevel-gear on said vertical shaft and driven by first-mentioned bevel-gear, a pinion on said vertical shaft, and a gear-wheel having a splined connection with the said revoluble spindle, and in engagement with said pinion.
